After the last Gulf war, his father used America's increased prestige to convene the Madrid conference, which led to the Oslo peace process.

OK, not much. But the point is, we made promises to our allies in 1991, which Bush I honored. As a result, from 1991 to about 1998, we had Iraq disarming under UN supervision, and a peace process in Palestine. It looked like a plan! Things have not worked out quite so well, but hindsight is 50/50, as a friend of mine once said.
